This is a fantastic heater. Made in Finland where it gets cold. Very industrial, clean, simple, safe, cool to the touch design. It is not a consumer product. I have several. I run them continuously 24/7 for months at a time. Have used it as the only heater in a 20' (interior length) travel trailer for several years. Use two when it gets down into the teens. Went off for a wander of the west in January and returned in May to discover that I had left the heater on high. Trailer walls, floors, ceiling much more than warm to the touch. This particular heater was hardwired to a 100' #12 extension cord.
This heater is not "Its just another 1500 watt electric heater"
All other 1500 watt electric heaters are just another 1500 watt electric heater!
They are available for substantively less than the price the OP referenced and are also re-branded by a couple of companies.
